Product catalog summary
Overview
The confocalLINE CLI8500 is a high-precision, high-speed confocal line sensor designed for 3D measurements. It combines confocal chromatic measurement technology with high-resolution line scanning, capturing up to 2,624 measurement points per profile. This allows for detailed 2D and 3D structure analysis on various surfaces, including reflective and transparent materials.

Key Features
  • High precision geometry scans on all surfaces with a compact design.
  • Direct output of measurement data via GigE Vision, fieldbus, and Ethernet.
  • Integrated SMART data evaluation within the sensor.
  • High point density with 2,624 points per profile and very high signal stability.

Technology
The sensor uses the confocal chromatic measuring principle, projecting a line of white light split into spectral colors onto the object. Each wavelength corresponds to a specific distance, allowing the sensor to determine surface distances and generate high-resolution height profiles and 3D point clouds.

Applications
  • Wafer topography measurement for detecting fine height differences.
  • Inspection of BGA solder balls for shape, height, and radius.
  • Geometric inspection during display assembly for surface shape and thickness.
  • Measurement of micro connectors and indexable inserts for quality control.
  • Inspection of medical implants for dimensional accuracy and potential deformations.

Technical Specifications
  • Measuring range (z-axis): 14.85 mm to 16.95 mm with a height of 2.1 mm.
  • Resolution: 200 nm (z-axis), 2.7 µm (x-axis).
  • Profile frequency: up to 10 kHz.
  • Interfaces: Ethernet, PROFINET, EtherCAT, EtherNet/IP.
  • Operating temperature: 20 to 30 °C.

Installation and Accessories
The sensor features easy installation with a centering mandrel and adapter plate for precise alignment. Various cables and accessories are available for integration into different systems.

Software and Integration
The CLI8500 supports direct measurement value transfer to PLCs, sensor control via standard protocols, and integration with vision software. It offers a comprehensive SDK and examples for various programming languages, ensuring flexible integration into custom workflows.

High performance light source More than 10 million Innovative technology for high-precision measurements points per measurement Deflection mirror The confocalLINE sensors use the confocal chromatic measuring principle, in which white light is split into its spectral colors by special optics and projected onto the measuring object as a line. Each wavelength of the spectrum corresponds to a defined distance. From the reflected light, the sensor determines the distance to the surface for each measuring point. The 2,624 measuring points per line produce a high-resolution height profile. By combining...
